MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 504,671, dated September 5, 1893.

Application filed April 17, 1893. Serial No. 470,536- (No model.)

To aZZ whom it may concern.-

Be it known that I, CONSTANT DORIOT, a citizen of the Republic of France, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Musical Instruments, of which the following is a specification.

My invention has relation to musical boxes,

to orchestrions and other similar instruments;

and it relates more particularly to the construction and arrangement of mechanism for permitting of the actuation of such instruments through the instrumentality of a suit- I 5 able motor.

The principal objects of my invention are first, to provide a musical instrument with simple, durable, efiicient and comparatively inexpensive mechanism and devices for permitting of the actuation thereof by means of an electric or other motor; second, to simplify the construction of a musical-box or similar instrument and to insure a positive action thereof; third, to provide differential mechanism for effecting the intermittent or oon-' tinuous actuation of a musical-box and for controlling by a positive movement the pincylinder with respect to its comb or combs; fourth, to provide a musical-box or similar 0 instrument with differential actuating mechanism controlled bya motor; fifth,to provide a musical instrument with devices and mechanism actuated by an electric-motor for imparting motion to and governing the speed 5 of a pin-cylinder with respect to its comb or combs with a switch for controlling the stopping and starting thereof; sixth, to provide a musical instrument with a detachable device for disengaging the actuating mechan- 4o ism thereof which is controlled by a motor from the driving shaft of the instrument; seventh, to provide a-musical box or similar instrument with mechanism adapted to be brought into engagement with and to 5 become disengaged from the main driving shaft of the instrument by simple devices and controlled by a motor through a'movable-switch adapted to contact with an insulating contact of a rotatable commuta- 5o tor on the driving shaft of the pin-cylinder thereof; eighth, to provide a musical instrument with detachable differential mechanism adapted to impart a rotary motion to the mainshaft of the instrument and controlled. by means of a motor in such manner that the rotation of the motor-shaft is difierentiated in respect to the driving-shaft of the instrument so that the speed or motion is positively and uniformly regulated from the motor; ninth, to provide a musical-instrument with a differential Worm-gear mechanism for imparting motion to and governing the speed of the instrument through the instrumentality of an electric-motor caused to engage with the driving mechanism thereof and controlled by means of a switch; tenth, to provide simple actuating mechanism for governing by a positive action the movement of the pin-cylinder with respect to its comb or combs by means of an electric-motor interposed in a circuit and controlled by means of a switch contacting with the makes and breaks of a rotating commutator mounted on the main drivingshaft of the instrument and the said actuating-mechanism adapted to be brought into and thrown out of engagement with the operative parts of the instrument by devices connected therewith; eleventh, to provide a musical instrument with differential worm gear actuating mechanism controlled by an electric-motor for imparting motion to the operative parts of the instrument and govern,- ing the speed thereof and provided with a switch or cut-out for stopping the same; and twelfth, to provide a musical instrument having a pin-cylinder mounted on a shaft with its com plemental comb orcombs actuated and governed as to the speed thereof by a wormgear differential mechanism controlled by an electric-motor in a line circuit from a gen- 9o erator'through a revolving commutator pro-f vided with makes and breaks and mounted on the pin-cylinder shaft and having brushes and a ma'nuahswitch contacting therewith,

the construction being such that the instru- 5 ment can be included in and excluded from" the circuit to respectively start and stop'ad libitum the same by means of said manualswitch. A

My invention consists of a musical instru- I00 ment provided with a differential gear and worm actuating mechanism, a speed controlling mechanism, a driving shaft controlling the tune producing devices, and a motor for actuating said mechanisms.

My invention further consists of a musical instrument provided with a shaft controlling the operative parts and having a speed controlling wheel mounted thereon and actuated by differential mechanism through the intervention of a motor.

My invention further consists of a musical instrument provided with a comb or combs, a pin-cylinder mounted on a shaft driven by a toothed speed controlling wheel meshing with a worm and counterworm-gear mechanism controlled by a motor.

My invention further consists of a musical instrument provided with a comb or combs, a pin-cylinder and its shaft and a gear-wheel driven by a differential worm-gear mechanism by means of a motor in a circuit having a commutator with insulating and conducting surfaces mounted on said shaft and a manual switch and brushes interposedin said circuit.

My invention further consists of the improvements hereinafter described and pointed out in the claims.

The nature, and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof; and in which Figure 1, is a top or plan view partly in broken section of a musical instrument embodying features of my invention; and Fig. 2, is an end view thereof.

In the drawings of which Fig. 1 is a plan and Fig. 2 an end elevation, at, is a horizontal bed plate provided with openings a and (t for the accommodation of the pin-cylinder b, and of portions of the mechanism for driving the same. This pin-cylinder b, is movable endwise upon its shaft 1), and is rotated by means of a post 5 penetrating an aperture in the head of the pin-cylinder b, and projecting from a disk b carried by the shaft b.

s, is a spring interposed between a toothed governor and speed worm-wheel 12 on the shaft 1), and the end of the pin-cylinder b, and tending to shift the latter toward the right.

b is a tune-changing cam pivotally mounted on the disk b and adapted to engage a pin or projection on the head of the pin-cylinder. This cam 11 is provided with a ratchet-wheel b disposed in range of a tune-changing lever which serves, when in the position shown in Fig. 1, to engage the teeth of the ratchet-wheel 19 Under these circumstances the movement of the disk causes the ratchet-wheel b, to shift the cam b whereby the cylinder 12, is shifted longitudinally.-

c, are one or more combs having their teeth vibrated by means of pins projecting from the pin-cylinderb. In this connection it may be remarked that the pins are omitted along an axial line so as to form a blank space I), opposite the teeth of the comb or combs 0, before the pin-cylinder is shifted in the direction of its length. Moreover, it is desirable that the instrument should be stopped with the blank space b opposite the teeth of the comb or combs c, in order to avoid accidental breakage or other injury that might occur to the teeth of the comb or combs, or to the pins of the cylinder, or to both, if the instrument had been stopped with one or more of the teeth in engagement with the pins.

d, is a worm-shaft journaled to the under side of the bed-plate a, and provided with a driving-screw d, having in the present instance a square thread.

6, in Fig. 2, is a bracket pivoted to a lug 6', depending from the bed-plate a, and adapted to be slightly rocked by means of a camlever 6 pivotally attached to an arm a depending from the bed-plate a, for purposes to be presently fully described.

f, is an intermediate worm-shaft jourualed at one of its extremities in bearings in the bracket 6, and supported at its other extremity by means of a conical screw center 6 carried by the bracket 8. This shaft f, is provided with a worm-wheel f, having in the present instance square teeth adapted to mesh with the square thread of the screw (1, and with a worm-screw f having in the present instance V-shaped teeth adapted to mesh with corresponding teeth on the worm-wheel b Rapid rotary motion is imparted to the worm-shaft (Z, through the instrumentality of the clutch g, and by means of a suitable motor, for example, the electric motor. In the present instance the shaft d, is assumed to make two thousand revolutions per minute, and drives the intermediate shaftf, through the instrumentality of the screw cl, and worm-wheel f at the rate of one hundred revolutions per minute, and the intermediate shaft f, in its turn drives the shaft 1), and pin-cylinder I), through the instrumentality of the screw f and worm-wheel b, at the rate of one revolution per minute. However, the rate of speed imparted by the mot-or to the shaft (1, and to the instrument may beincreased or diminished by rockingthe bracket e, through the intervention of the cam-lever e downward or upward as illustrated in Fig. 2 according to requirements. When the bracket e, is rocked downward, the teeth of the worm-wheel f, are slightly withdrawn from the thread of the screw (1, and the thread of the screw f is slightly withdrawn from the teeth of the worm-wheel b, so that the frictional resistance of the driving gear is reduced, with the result that the speed of the motor is permitted to decrease. \Vhen the bracket 6, is rocked upward the teeth of the ICO worm-wheel f, are pressed down upon the screw (1', and the thread of the screw f is pressed against the worm-wheel b, so that the frictional resistance of the driving-gear is increased with the result that the speed of the motor is permitted to increase. It may be remarked that the lever e afifords means, whereby the instrument may be stopped and started. However, for this purpose the bracket 6, must be shifted sufficiently to throw the intermediate shaft f, out of andinto action. The instrument may also be stopped and started by means of the clutch g, that servesto detachably connect it with the motor.

When use is made of an electric motor H,

for actuating the instrument, the terminals of the motor are connected by means of conductors 1 and 2, with insulated contact springs h, that sweep over conducting commutator disks 2' and t", insulated from each other, and mounted on and insulated from the shaft 1). The line conductors 2, 3 and 4, are in electrical connection with insulated pivotal contact springs j and j, adapted to sweep over the conducting commutator diskst'and i. These pivotal springs j and j are connected together by an insulating yoke 70, provided with an operating handle, whereby they may be shifted transversely of the commutator disks 1' and 2". When the springs j and j, occupy the positions illustrated in Fig. 1, the circuit entering at the conductor 3, may traverse the spring j, disk '6, spring h, conductor 1, motor H, conductor 2, spring h, disk t', spring j, and con ductor 4. However, when the springs j and 7", are shifted toward the left in Fig. 1, the spring j, is brought into range of an insulation Z, on the disk 11, so that the spring j, may ride upon this insulation 1, and thus break the circuit through the motor H, and cause the latter to come to rest. It may be remarked that the insulation Z, is disposed or positioned in such manner that it is adapted to engage the spring j, when the space b is opposite the teeth of the comb or combs a, so that if the spring j, is shifted toward the left, the instrument may continue to play until the space b comes opposite the teeth of the comb or combs, whereupon it will be stopped by the action of the insulation 1, upon the spring 7". This is important, because it insures the stopping of the instrument in such position that the pins of the cylinder 12, and teeth of the comb or combs c are not broken nor do they otherwise injure each other.

The mode of operation of the hereinbefore described musical instrument, is as follows: Current for driving the motor H, is supplied from the line of street conductors 3 and 4, through the springs j and j, the disks 1 and i, the springs h and h, and the conductors l and 2, as illustrated in Fig. 1, and the motor H, drives the shaft 1), and pin-cylinder b, at a uniform and comparatively low rate of speed through the intervention of the clutch g, shaft (1, screw d, worm-wheel f, shaft 1, screw f and toothed governor and speed worm-wheel b In order to stop the instrument the yoke k, is shifted toward the left, as illustrated in Fig. 1, thus bringing the springj', into range of the insulation Z, so that the latter, as soon as the space 1), comes opposite the teeth of the comb or combs 0, contacts with the spring j, and thus interrupts the circuit and stops the instrument with the pins of the cylinder b, clear of the teeth of the comb or combs c, and in a proper and safe position.

xIt will be obvious to those skilled in the art to which my invention appertains, that modifications may be made in the details thereof without departing from the spirit of my invention. Hence I do not limit myself to the precise construction and arrangement of the parts hereinbefore explained and illustrated.
